摘要
阐述了椰树攀爬装置的结构特点,并对其作业原理及工作过程进行了分析,介绍了声发射的试验原理与方法,并在空载、承重50 kg、承重75 kg以及承重100 kg四种工况下,对该装置进行了声发射试验,试验结果表明:该装置在作业过程中,声发射信号稳定,在不同承载工况下,信号幅值变化较小,其使用可靠性高,安全性能好。
This paper expounded the structural characteristics of coconut tree climbing device,analyzed its operating principle and working process and introduced the principle and method of acoustic emission testing under four working conditions of 0 kg,50 kg,75 kg and 100 kg loads. Such acoustic emission testing results showed that during operation of this device,acoustic signals emitted are stable with small signal amplitude change under different loads. In addition,its working reliability is high and safety performance is good.
